I have an old Universal Geneve Aero-Compax (link to pic on another thread below) that has a cal. 130 inside. The movement is actually based on a Valjoux 72.6 manual wind. After reading the Zenith thread about Zenith, Universal, and Martel watch companies I'm curious what was going on when Universal Geneve switched to Valjoux movements. Specifically:
- When did they move to Valjoux movements
- When they re-named the movements with Universal cal. #'s what (if anything) did they change?
